If a cube is rigged on all it's edges. How can I animate it so it tumbles forward forever?
For anyone who is interested in the future. I found a simple solution. Just add an 'empty' and make it a child of the cube (which behaves as a child to the armature). Make sure the empty is in the same location as the parent's bone head.
Give your parent's bone 2 constrains; 'Copy Rotation' + 'Copy Location' and make the target: the Empty.
